I ran into some problems with my earlier designs. Squaring off the rear of the receiver would leave no room for the web of your hand.
I had not realized this and was working on a Gen II version that had a 180B style rear end. This had the same problem as Gen I but also would not allow the BRN-180 to drop down into the receiver at the back.
I started fresh this morning and left the rear end alone and just modified the front to resemble the AR-180B/Nodak NDS-18S.
Astute observers may have noticed I also modified my pistol grip to fit on a standard AR-15 mounting point. I have had this request from some of my followers on Instagram.
By the way if you are on Instagram give me a follow. I post a lot of other stuff on there that you might like. Look up BigRix, the same as my Youtube channel.
The NoDak lower is still squared off in the back and has a bit of a taper for the pistol grip. Could you make it more like that? Also, since a buffer tube isn’t necessary could you build in a 1913 Interface that is compatible with a lot of the newer Sig MCX style stocks. Better yet, set it up for the whole ACE adapter pattern.
Hey Rick, any chance we’ll get a run of these made up?
